Thanks Tom and Mike for all your help.
Hopefully this helps out other newbiefs like me.
So here was my fix for not getting an ack decoded properly
Look in the manual it is very terse but should give you an idea of what to do.
Sets transmission audio level. This value should be selected to provide an appropriate FM deviation level, typically about 3.5 kHz

The audio level on his T2 was set so that his packets were not being decoded reliably by receivers (one of us could decode half of his packets, I could only decode one in ten or so). A quick tweak to the level improved matters so that I could always decode his packets, and I advised him to go through the process described in the manual for setting it optimally.
